APPLIANCE FOR GAS-LIGHTS.

Specification of Letters Patent.

Patented Mar. 1?, ifiitd.

Application filed April 7, 1913. Serial No. 759,485.

To all whom it may concern Be it known that 1. JOHN A. ABRAMS, a citizen of the United States, residing at lVadsworth, in the county of Medina and State of Ohio, have invented certain new and useful Improvements in Appliances for Gas-Lights; and I do declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gas lamps and more particularly to those of the inverted or upright type where the ordinary mantles are used.

The object of the invention is to increase the brilliancy of the incandescent mantles without increasing the supply of gas.

A further and important object of the invention is in the provision of a lamp of the character referred to whereby the mixed air and gas is conveyed to a mixing chamber and primarily heated before the same is supplied to the burners.

A further and important feature of the invention consists in the particular construction of the mixing chamber which is composed of a lower convex or bowl shaped bottom forming diverging walls, said chamber having a concaved top, whereby the mixed air and gas is properly directed or otherwise deflected to the movable plurality of fixtures mounted upon said chamber.

lVith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings: Figure 1 is a central vertical section of the complete invention showing the greater portions of the fixture in side elevation. Fig. 2 is a perspective view of the chamber which receives the mixed air and gas. Fig. 3 is a side elevation of the lower portion of the mixing tube which forms a partof the chamber. Fig. 4 is a detailed side elevation of a modification of the invention showing an upright burner attached thereto.

In the embodiment of my invention 1 represents a mixing tube of conventional construction which is adapted to be attached to a gas supply pipe in usual manner. Mounted upon and forming an integral part of said tube is a mixing chamber 2 Within which the mixed air and gas is expanded before entering the burners mounted upon said chamber. chamber for the air and gas is bowl shaped or otherwise provided with a convex annular wall 3 which forms an integral part with the concave top 4 which forms closure for said chamber, whereby the mixed air and gas is properly deflected toward the outer annular edge of the chamber to which the gas fixtures are removably attached. Projecting from the top at of the mixing chamber 2 are a plurality of nipples 5 having the reduced upper ends 6 forming shoulders 7 which are located a suitable distance above the top of the chamber for the purposes hereinafter described.

The gas fixtures which form a detachable part of the mixing chamber and construe tive features thereof are especially arranged for the purpose, and consist of semi-circular shaped pipes 8 the connecting ends of which are revolubly and adjustably mounted upon the reduced upper ends of the nipples 5 with their lower edges in contact with the shoulders 7 of said nipples, whereby said pipes are held in a rigid position in respect to the chamber. The outer ends of the gas conducting pipes are flanged as shown at 9 whereby the usual ordinary fixture containing a mantle may be readily attached to the same.

As clearly shown the mantles 10 or other light producing means are located in close proximity to the mixing chamber 2 into which the mixed gas and air is conducted, whereby said chamber is properly heated, thereby increasing the brilliancy of the lights by removing the moisture from the air or gas, and further producing a fixture which is ornamental and durable.

By the construction and connection of the parts as herein shown and described it is clearly evident that the conducting pipes 8 may be adjusted to and from the mixing chamber 2 whereby the latter may be supplied with a proper amount of. heat for the purposes previously described. It is further evident that by the particular construction of the mixing chamber 2 the mixed air and gas is properly conducted through the plurality of nipples located adjacent to the annular edge of said chamber and to the supply pipes 8 leading to the mantl s 10 or other fixtures for supplying light.

Should it be desired for any reason to supply the device with a new fixture including the supply pipe 8 it is clearly evident which are The mixing that the same can be quickly and readily removed from the nipple 5, and a new pipe together with a lighting fixture readily replaced.

The particular construction of the nipples 5 as clearly shown in Fig. 1 supports the connecting ends of the fuel supply pipes a suitable distance above the concaved top of the chamber 2, whereby said pipes may be readily adjusted in the manner previously described and for the purposes set forth.

In Fig. & a modification of the invention is shown wherein an upright burner is removably secured in a like manner to the nipple projecting from the mixing chamber 2 and it is to be understood that in either construction shown, a plurality of mantles may be secured to the fuel supply pipes without departing from the nature of the invention.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the claimed invention. 7 What is claimed is:

1. In combination with a mixing tube adapted to be secured to a gas supply pipe, a mixing chamber mounted upon and se- Copies of this patent may be obtained for five cents each, by addressing the Washington, D. 0."

cured to said tube, said chamber being bowl shaped and having a concaved top, nipples secured to and projecting from the concaved top of said chamber and located adjacent to the annular edge thereof, and fuel supply pipes detachably mounted on said nipples and provided with light producing mantles.

2. Ina lamp the combination with an air and gas mixing tube, of an enlarged mixing chamber into which said air and gas is conducted and expanded, said chamber being bowl shaped and having a concaved top, a plurality of nipples secured to said concaved top of the chamber and located adjacent to the annular edge thereof, said nipples having upper reduced ends terminating in shoulders, the latter being located above said top of the chamber, and fuel supply pipes adapted mounted upon the reduced ends of said nipplesand located above the top of the chamber by the shoulders of the nipples, said pipes being semi-circular in shape, and light to be adjustably and removably' supplying devices secured to the outer ends of said pipes.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
